vol_balok

该程序利用Matlab编写，并带有GUI截面。实现了任意格式图像压缩的功能。并且可以对比显示压缩前后图像，显示压缩比例和压缩时间。(The program prepared by the use of Matlab, and with a GUI cross-section. Image compression format to achieve an arbitrary function. Compared before and after the show and can compress the image, showing compression ratio and compression time.)
